Verifying and Troubleshooting ISM Line Card and SAM Installation
After installing the hardware, you need to look at the LEDs on the Flashback Service Acceleration Modules (SAMs) to verify that the ISM (Integrated Service Module) line card and the Service Acceleration Modules (SAMs) were installed correctly. If they were not, you need to troubleshoot to find the problem. The following sections provide information about how to verify and troubleshoot ISM (Integrated Service Module) line card and Service Acceleration Modules (SAMs) installations:
Troubleshooting using Cisco IOS XR commands is briefly described in the “Configuring and Troubleshooting the Service Acceleration Modules (SAMs)” section.
Initial Boot Process
During a typical ISM (Integrated Service Module) line card boot process, the following events occur:
1.
The ISM (Integrated Service Module) line card receives power and begins executing initialization software.
2. The ISM (Integrated Service Module) line card performs internal checks, and prepares to accept the Cisco IOS XR software from the RSP.
3. The RSP loads the line card with its Cisco IOS XR software.
To verify that the ISM (Integrated Service Module) line card and Service Acceleration Modules (SAMs) are working properly:
Step 1
Check that the SAM Status LED is on (green) to verify that the card is operating normally.
Step 2 Check that the SAM Attention LED for the SAM you’re troubleshooting is off (not lit red) to verify that there is no SAM error and that the SAM does not need attention. If the SAM Attention LED is lit red, there may be an error. If the SAM Attention LED is flashing, someone has pressed the Shutdown Button.
Step 3 Check that the SAM Flash Module Fault LED for the SAM you’re troubleshooting is off (not lit red) to verify that there is no SAM Flash Module Fault error and that the SAM does not need attention. If the SAM Flash Module Fault LED is lit red, there may be an error.
Step 4 Check that the SAM Attention LED for the SAM you’re troubleshooting is off (not lit red) to verify that there is no SAM error and that the SAM does not need attention. If the SAM Attention LED is lit red, there may be an error. If the SAM Attention LED is flashing, someone has pressed the Shutdown Button.
Step 5 If one of the conditions above is not met, refer to the “Advanced ISM (Integrated Service Module) Line Card and Service Acceleration Modules (SAMs) Troubleshooting” section to identify any possible problems.
Status LEDs
You can use the SAM Status LED , the SAM Attention LED , the SAM Flash Module Fault LED, or the SAM Flash Module Active LED on the Service Acceleration Modules (SAMs) front panels to verify proper operation or troubleshoot a failure (Refer to Table 2-1 through Table 2-4 ).

Indicates that the SAM has one or more flash module faults present. |
Troubleshooting the Installation
If the the SAM Status LED , the SAM Attention LED , the SAM Flash Module Fault LED, or the SAM Flash Module Active LED on the Service Acceleration Modules (SAMs) front panels indicates some issue, there is either a problem with the line card installation or a hardware failure. To verify that the line card is installed correctly, follow these steps:
Step 1 If a Port Status LED fails to go on (no activity), but the Card Status LED is on, verify that the initialization sequence has completed successfully. If this is the case, verify that the interface is not shut down. If the interface is not shut down, suspect a circuitry problem with the Port Status LED and contact a service representative for further assistance.
Step 2 If the Card Status LED fails to go on, check the router connections as follows:
a. Verify that the line card board connector is fully seated in the backplane. Loosen the captive installation screws and firmly pivot the ejector levers toward each other until both are parallel to the line card faceplate. Tighten the captive installation screws.
b. Verify that all power cords and data cables are firmly connected at both ends.
c. Verify that all components on the card are fully seated and secured to their sockets.
After the line card re initializes, the Card Status LED on the line card should go on. If the Card Status LED goes on, the installation is complete; if the Card Status LED does not go on, proceed to the next step.
Step 3 If the Card Status LED still fails to go on, remove the line card and try installing it in another available line card slot.
- If the Card Status LED goes on when the line card is installed in the new slot, suspect a failed backplane port in the original line card slot.
- If the Card Status LED still does not go on, halt the installation. Contact a service representative to report the faulty equipment and obtain further instructions.
Step 4 If an error message displays on the console terminal during the line card initialization, see the appropriate reference publication for error message definitions.
If you experience other problems that you cannot solve, contact a Cisco service representative for assistance.
Configuring and Troubleshooting the Service Acceleration Modules (SAMs)
After the person who installed the hardware verifies that the new Service Acceleration Modules (SAMs) are installed correctly by examining the LEDs, the network administrator can configure the Service Acceleration Modules (SAMs). The following sections provide information on configuring and troubleshooting the Service Acceleration Modules (SAMs):
- Configuration Parameters
- Line Card Interface Address
- Using Configuration Commands
- Basic Line Card Configuration
- Advanced ISM (Integrated Service Module) Line Card and Service Acceleration Modules (SAMs) Troubleshooting
Configuration Parameters
Table 2-5 lists the default configuration parameters that are present on the the ISM (Integrated Service Module) line card and Service Acceleration Modules (SAMs). Refer to Cisco IOS XR software documentation for complete information about these parameters.
Line Card Interface Address
A Cisco ASR 9000 Series Router identifies an interface address by its rack number, line card slot number, instance number, and port number, in the format rack/ slot /instance/ port . The rack parameter is reserved for multirack systems, so is always 0 (zero) for the Cisco ASR 9000 Series. The line card slots are numbered from 0 to 7.
Instance numbers are reserved for cards that have subslots. This parameter is currently always 0 (zero) for line cards in the Cisco ASR 9000 Series. The ports on the line card are numbered 0, 1, 2, and so on. For example, the rack/ slot /instance/ port address of the fourth port of a line card installed in line card slot 1 is 0/1/0/3. Even if the line card contains only one port, you must use the rack/ slot /instance/ port notation.
Using Configuration Commands
The command line interface (CLI) for Cisco IOS XR software is divided into different command modes. To configure a line card, you enter the correct mode and then enter the commands you need.
When you first log in, you are automatically in EXEC mode. Next, enter the configure command to access configuration mode. Then, enter the interface command to enter interface configuration mode and specify the interface. You are now in the command mode where you can configure the new interface. Be prepared with the information you will need, such as the interface IP address.
Basic Line Card Configuration
The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration.
The following example shows one way to configure the basic parameters of a line card:
Step 2 Check the status of each port by entering the
show interface
command:
Step 3 Enter global configuration mode and specify that the console terminal will be the source of the configuration commands:
Step 4 At the prompt, specify the new interface to configure by entering the
interface
command, followed by the
type
(for example,
gigabitethernet
or tengige)
and rack/
slot
/instance/
port
(line card rack, slot number, subslot number, port number). Remember that Cisco ASR 9000 Series rack and subslot values are always 0 (zero). For example, to configure port 4 on an 8-Port 10 Gigabit Ethernet line card in line card slot 1:
You are now in interface configuration mode.
Step 5 Assign an IP address and subnet mask to the interface with the
ipv4 address
configuration subcommand, as in the following example:
Step 6 Change the shutdown state to up and enable the interface:
The no shutdown command passes an enable command to the line card. It also causes the line card to configure itself based on the most recent configuration commands received by the line card.
Step 7 If you want to disable the Cisco Discovery Protocol (CDP), which is not required, use this command:
Step 8 Add any other configuration subcommands required to enable routing protocols and adjust the interface characteristics. Examples of such subcommands are:
Step 9 When you have included all the configuration subcommands to complete the configuration, enter the
commit command to commit all changes you made to the running configuration.
Step 10
Enter Ctrl-Z
(hold down the
Control
key while you press
Z
) to exit configuration mode. If you did not enter the commit command, you will be prompted to do so:
Answer yes to commit, no to exit without a commit, or cancel to cancel the exit (default).
Step 11 Write the new configuration to memory:
The system displays an OK message when the configuration has been stored.
Advanced ISM (Integrated Service Module) Line Card and Service Acceleration Modules (SAMs) Troubleshooting
This section briefly describes advanced troubleshooting commands that can be used in the event of an ISM (Integrated Service Module) line card and/or Service Acceleration Module (SAM) failure.
Note This section assumes that you possess basic proficiency in the use of Cisco IOS XR software commands.
By using the commands listed in this section, you should be able to determine the nature of the problems you are having with your line card. The first step is to identify the cause of the line card failure or console errors that you are seeing.
To discover which card may be at fault, it is essential to collect the output from the following commands:
Along with these show commands, you should also gather the following information:
- Console Logs and Syslog Information—This information is crucial if multiple symptoms are occurring. If the router is configured to send logs to a Syslog server, you may see some information on what has occurred. For console logs, it is best to be directly connected to the router on the console port with logging enabled.
- Additional Data—The show tech-support command is a compilation of many different commands, including show version, show running-config, and show stacks. This information is required when working on issues with the Cisco Technical Assistance Center (Cisco TAC).
For examples of how to use these commands and the resulting output, refer to the Cisco ASR 9000 Series Troubleshooting Guide.
Note It is important to collect the show tech-support data before doing a reload or power cycle. Failure to do so can cause all information about the problem to be lost.
Note Output from these commands will vary slightly depending on which line card you are using, but the basic information will be the same.
Collecting SAM Information
Here is the example output for the show platform command:
Here is the example output for the show platform summary location command:
Here is the example output for the show inventory command:
Below is a description of fields for the show hw-module fpd location all command.
- Location: Location of the LC.
- Card Type: Type of the AVSM or SAM card, “TBD”.
- Type: LC or SAM.
- Subtype: FPGA, ROMMON, BIOS or FW.
- Instance: A unique ID used by the FPD process.
- Current SW Version: Currently running FPD image.
- HW Version: Hardware version of the card.
- Upg/Dng: Specifies whether an FPD upgrade or downgrade is required. For BIOS and SAM upgrades this is dependent on the underlying hardware version.
Here is the example output for the show hw-module fpd location all command:
Here is the example output for the show hw-module fpd location 0/1/CPU0 command:
If the upg/dng? column says Yes, it means that one or more FPD needs an upgrade or a downgrade. This can be accomplished using the admin upgrade hw-module fpd command.
Here is the example output for the show hw-module fpd location 0/1/SAM0 command:
Here is the example output for the show hw-module fpd location 0/1/SAM1 command:
Similarly for the show fpd package command the output fields are:
- Card Type: Type of the ISM or SAM card, “TBD”.
- FPD Description: Description of all available FPD packages for the card.
- Type: LC or SAM.
- Subtype: FPGA or ROMMON, BIOS or FW image names, these are the values used in the upgrade hw-module fpd command.
- SW Version: FPD software version required.
- Min Req HW Version: Minimum Hardware version for the associated FPD image
Here is the example output for the show fpd package command:
